Despite a contract that expired Sunday, Waste Management of Alameda County and the union that represents nearly 500 garbage workers throughout the East Bay have no plans to head back to the negotiating table.

Representatives for both Waste Management and Teamsters Union Local 70 — which represents the company’s drivers and equipment operators — said contract talks Sunday were unproductive and no new negotiations have been scheduled.

Despite the lack of progress, Teamsters Local 70 Secretary-Treasurer Chuck Mack said Monday that no deadline has been set for a strike.

The union and garbage company have butted heads over what the unions says are job cuts and unfair safety and collective bargaining provisions.

David Tucker, spokesman for Waste Management, said the union has yet to come to the company with any counterproposal to address some of the union’s concerns — which are stricter rules for driver safety and disciplinary actions for those who don’t abide.

“We continue to reach out and try to get them back to the table,” Tucker said.

Mack disagreed, saying Waste Management has set its own agenda to make cuts in the proposed contract and has shown unwillingness to negotiate.

“Talks have been fruitless,” Mack said.

Mack added that while the union has no plans to strike, he has heard from other unions that Waste Management plans to lock out workers.

Tucker said he has no knowledge of any such plans.

Waste Management handles trash pickup for more than a dozen East Bay cities, including Oakland, Livermore, Hayward and parts of Castro Valley.
